How to issue certs for multiple domains with different webroots with acme.sh?

@MikeMcQ oh, I see. I added the server as letsencrypt like --server letsencrypt at the end of the acme.sh command but I get the below error:

My acme-challenge folder looks like below:

Do I need to do something else to switch to letsencrypt like registering my acme.sh with letsencrypt or something?
